SPARE-TIRE CARRYING AND RIM-REMOVINGDEVTCE.

. Application filed July 22, 1924. .Serial No. 727,511.

To all whomit may concern:

Be it known that I, FRANKLIN A. HAMIL- TON, acitizen of the United States, residing at Three Forks, in the county o-f'Gallatin and State of Montana, have invented certain new and useful Improvementsin Spare-Tire Carrying and Rim-Removing Devices, of

which the followin 'is a specification.

This invention re ates to a spare the carrying and rim removing device designed to be carried upon motor driven vehicles.

This invention is an improvement upon the structure disclosed in the 'all'owedl atent No; 1,499,156,-which issued June 24, 1924.

The primary object of this invention is the provision, .in amanner" as hereinafter set forth, of a spare tire carrier for motor driven vehicles havingcombined therewith a means whereby a rim carried upon the carrier maybe easily broken and a tire removed therefrom, easily and quickly withoutthe necessity of laying the tire and the rim upon the ground as isnecessary in the present method. I

Another object of the; invention is the provision, in a manner as hereinafter set forth, of a spare tire carrier forgmotor vehicles, having means whereby the throwk ing of a single lever will release :the tire for removal from the carrien'and further having means whereby asinglethrow' of the, same lever, after proper adjustment of certain parts of the carrier, will break the rim, of a tireto allow the same to be 're movedtherefrom withouttaking the rirn'from the carrier.

A still further object of this invention is the provision, in a manneras hereinafter set forth, of a spare tire carrier for, motor,

vehicles so constructed that by the throwing adjustment of certain parts of the carrier, a

tire rim may be broken and indefinitelyheld in the broken position to free both hands-of the operator while he lifts the released tire v i tion is the provision, in amanner as-fhereinfrom the broken rim. p

This invention contemplates ofan upright substantially V-shaped mem-v ber connected between its divergentgfree ends by an arcuate shaped? bar, witheachv divergent end carrying thereon a transve tires and rims from the carrier.-

ciently' to the provision head; which -in turn carries two or more cradle members adapted to receive a tire mm. ,This iV-shaped member. is rigidly sevcured in positionupon the body of a vehicle and it has working vertically througlifthe lower {portion or apex "thereof Ta} incrimiwhichslikewise, carries at its free lower end a shiftable: foot memberin turn carrying;

two or more cradles similar to those above referred to. ,The said foot isthreaded upon the rack bar to allow it to be adjusted for any sizev rim, which one might desire to carry upon the carrier. 'A pinion is'p'iv-' otally. supported infr'ontof the carrier at the central portlon thereof, that is, at the apex ofjsaid V-shaped member, andjthis pinion'engages the said rack bar and has extending therefrom av lever'w hicli when swung up or down, raises or lowers the rack bar and thefoot carried at the lower end thereof to release or clamp a rim in position i upon the carrier. Mean'sjis provided for locking the bar to prevent the removal of V Carried upon'the shiftable ,foot and alsoupon. and

atthe central portionof the arcuate-connectlng bar .;-1's a-f shiftable hook *member adapted'to be engagedbv-er the. edge, of atire rimwhen it"is desired to break the rim 'to remove a tire therefrom; VVhenthes-e hook'members are'engaged over the of shiftable foot,'-insteadof coming free "from the run, will draw the rim upwardly with i it''upon one side of the point at which it breaks and thus contract the same alow the t re to be removed there-V 7 from. y

Provision ismad'e for holding-the swing- I in}; bar in position with-the foot raised and arim,,and the s'aidleverswungdownwardly j torevolve t'h'e pinlonf'and lift therack, the I the rim in broken position so that both hands of the operator maybe free to work upon the tire, and provisionis also made to prevent the hook members from rattling and becoming noisy'when they are disengaged from the rimsupon the carrier and the ma- .chine'carrying the same is in motion;

A furtherand final object of this inven strengthzgand,durability, neat iand attractive;

in appearance, easily operated and inexpensive to manufacture and set up. I

The invent-ion will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding that the invention is not confined to any.

strict conformity with the showing of the drawings but may be changed and modified so long" as such changes and modifications mark no material departure from the salient features of the invention as expressed in the lly'iPOlMlQtl claims.

in the drawings:

F igure 8 is a detail perspective View of a locking dog which operates to securecertain parts of the device when the same is hold ing a rim in broken condition upon the carrier.'

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts'throughout the several views of the drawings, there is shown a substantially V-shaped body member, indicated a whole by the numeral 1, which body member has associated therewlthand de pending from the apex thereof a lower vertically shiftable structure,indicated as a whole by the numeral 2. r

The member 1 wiiciax inc ,g'tne' a b mrgi h l r ye rel toge "1 t he come e1 t lower ends by the substantially triangular plate ifhese arms 3 and i are preferably made of tubular material as this structure will greatly lessen the weight of the finished device and will not detract trom the strength of the device shown as being split at their low er'ends to a plate 5 to ertend therethrough and The arms 3 and are here allow tl be seen pfl in positionby means ct the rivets (3. l-lowever, applican does not limit him-v self to thisstructure for the plate 5 and the structure it it is desired to do so. 7

The plate is enlarged through its central portion as indicated'at Tend the vertical rectangular aperture '8 is tormed through shown in Figure comprises a pair of up; wardly divergent arms 3 and a, respectively,

arms 3 and 4 maybe cast as an integral this enlarged portion and extends throughout the length of the plate opening at the upper and lower portions thereof. The purpose of this passage 8 will become apparent as the description of the device proceeds.

Extending between and connecting the divergent arms 3 and a at a point adjacent their upper ends, is a brace bar 9, here shown as having itsends'turned about the arms and secured thereto by means of the rivets 10. This brace bar may, however, he formed integral with thearins 3 and at in the same manner as-the plate The central portion of this bar 9- is enlarged as at 11 and has termed thereth'rough a verticalslot l2, s

of the drawings. Upon the terminal upper end of each ot the armsi'l and d, there is secured a channel ot' the arm is inserted and secured. Each of these heads 1?) has secured thereto one, two or more cradles 13 across and in which a tire run 16 is supported.

Secured upon the back of the plate 5 is a V vertically positioned sleeve 17 having the laterally extending wings 18, which are secured across and between the lower portions of the arms 3. and land acrossthe enlarged portions 7' of the plate. Upon each of the arms 3 and'd' adjacent the underside of the head carried thereon, is a similar sleeve member 19 which extends longitudinally of and parallel with the arms to -W1lCl1 it is attached by means of the outturned portions 20 which are riveted to the arms or other-j wise secured thereto in any appropriate manner. Thesesleeves 17 and 19 are adapted to receive therein the right angled end portions .21 of supporting b'ars22 which extend and i are secured to the body or the machine upon which the device'is carried.

Extending between the head members 13 which are carried upon the terminal ends of the arms, is an arcuate bar oi substantial size as indicated at 23, this bar has its terminal ends turned downwardly at right angles as indicated at 24 and secured by means of the rivets 25 to the inner race of one of the heads 13. 1 This arcuate bar 23 has formed through the central portion thereot at ZtPOlIli'i midway between its ends and directly above the passage 8 in the plate ran aperture 26. Extending through this aperture 26 is a reduced portion 27 of the of the shank 28, is an arcnate'spring which 15 formed upon a lesser are than the member 23 and this spring 30 has its ex tended ends provided with the overturnec side ears 31, wh ch clamp over the edge ot the' bar 23 and secure the spring thereto.

lli).

This spring has a normal tendency to rise upwardly at the central portion against the shank 28 which draws the finger nut 32,

which is threadably carried upon the lower end'of the reduced portion 27,11 against the underside of the bar 23 and thus prevent the hook member from rattling when the.

tical reciprocation in the passage 8 of the enlarged portion 7 ofthe plate 5 is arack bar 33, the lower end of which is reduced and provided withscrew threads as indicated at 34.

' At the lower end of the threaded reduced portion 34, of the rack bar 23 is a foot'35 similar to the head members 13 and like thesemembers, formed of channel iron material, and this foot has at its central por tion in the channel between the walls thereofa block 36 having a central bore therethrough, which bore at its upper and outer end, is ofsmall diameter as indicated are? and threaded to receive the reduced portion 34, and at its lower end is of a large diameter as at 38 to receive therein a collar 39which is secured to the end of the reduced portion 34 and acts to prevent the same from being Linscrewedl or disconnected fromthe block As clearly shown, upon ward the inner face oftherim carried on the carrier. 'Thefoot 35, likethe members 13,"has secured thereto cradleanembers 40' which cooperate with thecradles 15, carried up to engage one of the rims 16 carried in the cradles 15 and 40.

Extending over and bridging the lug 41 is an arcuate spring 46, the ends of which are turned slightly'as at 47 and bear against the back of thecradles 4O. This spring 46 has a central aperture therethroughmidway the ends thereof and the'reduced portion 42 of the shank 43 extends through this aperture, and this spring bears against the under side of the finger nut 45 and normally tends to raise the hook 44 until the shank43 en- 7 gages the underside of the lug 41 and. holds the same in this positionto prevent the rat to provide a hand grip.

reference toFig ure 'l'orto Figure 3, the foot 35 has its channel directed upwardly," whereas the heads 13 have their channels directed downwardly, thusturning the faces of-the channel members outwardly and directingthem to? tling of the hook member when disengaged from the rim '16 and when the machine carrying the device is in motion. p

The: lower portion of the outer wall of the passage 8 is cutaway as at 48, and extending outwardly from each side of this cutaway portion is an-apertured'ear 49. These cars are in alignment and the apertures therein are in alignment and there is positioned between these cars the small gear. pivotally 'mounted therebetween upon the pivot pin 51.

The teeth of this gear 50 engage the teeth ofthe rack bar 33 as shown in Figure 6,; I

and there is'extended from the periphery ot th s gear the arm or lever 52 which s enlarged or looped at its outer (:Il Cl' El-SJ at 53 The inner side of t-he'lever 52 has formed thereon the aperturetl'lug 54 which, when the lever is'inraised or upright position,

1 extends through the apertu-re'12 in the cross bar 9 and is adapted to have passed there i througha lock or other securing element to lock the tire carrier. .It will be seen that when the lever 52 is drawn downwardly, the

sage 8, to lift the foot from engagement with therims 1 6 as shown in Figure 3, and either of the rims can then be removed from'the carrier. i preventing the-same from entirely passing through the bore 37.

Pivotally secured to the outer face of the plate 5.is a'locking dog ,55having' an aperture 56 therethrough for the pivot pin, a nd this dog normally extends horizontally across the "plate asfshown in Figure1and has upon its inner end, which s positioned over the gear 50, thej'enlarged qdepending head57, the lower face of wh ch IS CUTVGil and provided withteeth 58. 1 Thefother end of the dog isturned outwardly as at 59 to provide finger grip." The curvefin the lower face of the head 57 corresponds to 'thefl. curve ofthe gear50, and'a's shown in ll igure j 6, it is intended that when the teeth 58 engage with the teeth of the gear 50, they will; fol-.

9O rack bar 33 will be raised through the pas- 7 low the curvature of the. gear and thusjhave allof their teeth in engagement with the U gear, at the same time causing the backof the dog to lie 'fiat against the plate as is" This dog is' clearly shown in this figure. used asv a locking device for the gear 50and the rack 33 to retaln-the same 1n a set pos tion during a certain'operation of the device" which operation will be described.

The operation of this device is as follows: After the carr er has' beensecured III-P0814 tion'upon the body ofthemotor vehicle, and Y it is desired to place the extra or spare tires thereon, the foot 35 is revolved to raiseor lower the same upon the reduced portion 34 of the rack bar to suit the same to the size of rim which is to be carried upon therack. w

The lever 52 is then releasedfrom engage ment with the crossbar 9 and {swung outwardly and downwardly to. ev lve the "gear flhreakingdt from engagement with the ad- 'by the foot in position, as is also shown in Figures,

Wheel 50 and raise the rack bar 33, which in turn lifts the foot 35. The spare tires and rims are then seated across'the cradles carried by the heads 18,. and when hung in this position the lowermost portion thereof will be directly below the cradles 40 carried The lever bar'52 is then swung upwardly to force the rack bardownwardly and also the tool-. 35 until the'cradles l engage or seat over the rim of the. tire carried upon the rack. A padlock may then be secured throu 'h the a)erture of the 111 b h 54; atter the same has passed through the aperture 12 in the. cross bar 9 and the spare tires and runs will then be lockedsecurely in position upon the carrier.

hen it is desired to remove atire from a run. the rinrand tire is shltted across the cradles 15 and 4-0 to position the breaking point of the rim adjacent one side of the foot 35. The hook member 29 at the upper portion of the carrier 13 then turned toengageover the inner edge of the rim 1.6. as

volve theegear' wheel and raise the'rack 33. hen the rack. 33 is raised the foot 85 1s naturallydrawn up. with it, and due to the fact that the hook l is carried by the foot the same comes up with the toot and draws one endot the rim '16 with it, thus jacent other end, as shown in Figures 1 and d 'lVhen the rim 16 has been broken sutiiciently to allow for the easy removal of the tire therefrom, the dog which has previously been lifted upwardly to disengage it from the rear wheel. 50, is allowed to drop I hereto.

of the head 57 engage the teeth of. the gear .until the teeth 58 formed in the loweirtace wheel 50 as shown in Figure 6,. wedging the 1 head 57 between the gear wheel and the outer face of. the plate 5. In. this position the gear wheel 50 is effectively prevented from reversing itself to allow the rack bar to slip down under the tension of the sprung rim, and both hands of the operator are, tree to remove the tireand repair or replace the same as desired, while the rim is held in broken position ready for the easy replacerent of the tire thereon. mg the operation of breaking theirim 1 6,

The hook 29, dur-.

prevents the rim from being lifted upwardly thereof is drawn upwardly by the hook 44. From the foregoing description it may be seen thata novel, eflicient and serviceable from the cradles 15 when the lower aortion tire carrier and rim removing device/is provided which is handy and convenient atv all times, and which can be. easily and quickly; operated to remove a run from a tire without the muss and hard work consequent to; the

removing of tires from rims as in themethod at present in use.

Having thus described my invention what.

(I claim is:

A tire carr er of the character described,

comprising a plurality of heads-spaced inner and outer cradles supported across .sard

heads, one ot the heads being adjustable relative to the other, an arched bracketsecured to a pair of the heads and located cradles thereon, an eye on the remaining head medially thereof, adjustableand rota; .table hooks carried by the bracket and eye,

and adapted to be positioned. alternately; with respect to the inner and outer cradles to engage rims thereon, and means for moving the adjustable head. V
